Stephen Porges’ Polyvagal Theory significantly reworks our understanding of how the nervous system responds to threat and trauma. This relatively new understanding of the Autonomic Nervous System (ANS) – called Polyvagal Theory – can allow us to assist children, patients, and ourselves, toward greater wellness. ANS is a continuum between two ‘poles’: the Sympathetic Nervous System (SNS) at one end; and the Parasympathetic Nervous System (PNS) at the other. In that earlier understanding of the ANS, there was the common assumption that the SNS referred to the person’s “Fight or Flight” response, while the “Rest and Rebuild” response occurred as a result of PNS function.
